Form of the three-stage cyclone separator in the catalytic unit and replacement cycle

Ours is the same as the original owner’s, but our newly designed catalytic triple cyclone is located inside the settler. Where is yours?

I’ve never heard of this form; could you tell me more about it?

The energy recovery system in catalytic cracking units is often used as multi-tube cyclone separators with three cyclones. The three types of cyclones currently in use in our country are the swirl-type cyclone, the vertical-tube multi-tube cyclone, and the horizontal-tube multi-tube cyclone. The vertical tube type three-rotor and horizontal tube type three-rotor are more commonly used. (1) Types and performance of vertical three-cyclone cyclone tubes. For vertical three-cyclone systems, guide vane-type cyclone tubes are commonly used, as they facilitate even distribution of gas flow and allow for a high processing capacity per tube. However, this approach limits the efficiency of separating fine particles; therefore, efficient guide vane-type cyclone tubes are crucial for vertical three-cyclone systems. The most widely used vertical three-cyclone dust collectors in China are the EPVC series, PDC type, and PSC type of cyclone collectors developed by China University of Petroleum. There is also the VER series from Luoyang Petrochemical Engineering Company, and the Shell series from the American company Shell. As well as the VAS-type and PST-type cyclone tubes that have emerged in recent years. (2) Types and performance of horizontal tubular three-cyclone dust collectors. After the 1990s, a task force in our country, composed of the Science and Technology Development Department of Sinopec, China University of Petroleum, Sinopec Construction Engineering Company (formerly Beijing Design Institute), and Luoyang Petrochemical Engineering Company, also independently developed horizontal tube-type three-rotor units of the PHM type (horizontal lying tube type) and PIM type (obliquely placed lying tube type).

Are you from Dongying too? Is it because there are many local refineries in Dongying?

Has the newly designed three-spin device been put into use? Is it used by anyone other than you? Are there any other devices that use it?
